Opening your Hyundai's window is made incredibly simple by the Hyundai window motor. Nestled within the door panel, the Hyundai window motor is connected to the window regulator and creates the power that it relays to the regulator. This is what allows your window to go up and down at minimum effort to you. Mostly, a defective Hyundai window motor is caused by water damage and ironically enough, this occurs when the window is left open while it is raining and rain seeps into either the arm rest control panel, or through the door panel if the window seals are not intact. This can be prevented with a Hyundai vent visor.
